Part 3: Real World Field Tests now up on the channel: https://www.youtube.com/watch?v=5jl8vHHn7_s
This open source turbine can be built for about half the cost of a 120 watt solar panel, and will produce about ten times the power per day. It can be plugged into any appropriate waterway without the need for earthworks, and uses only basic off the shelf and recycled materials, and basic hand tools.
The turbine is now working and producing power.

This technology was produced in partnership with COACT, an open source green tech incubator in Barcelona. COACT exists to help all kinds of innovators working on green technologies. To learn more, and apply for a residency visit https://www.coactlab.org
And thanks to the good people at Ca La Fou (https://calafou.org/) for the rest.
Once the design is optimized I’ll produce a full open source construction tutorial on
the website: https://opensourcelowtech.org

and the Facebook group (which is the main discussion forum): https://www.facebook.com/groups/opensourcelowtech/
My name is Daniel Connell. I prototype and develop basic technologies which anyone can make using recycled materials and simple tools.
The aim is for everyone everywhere to be able to build and maintain their own infrastructure; producing their own energy, food, clean water, communications, and anything else they need.
All designs are open source and license free for any purpose, and full construction tutorials and how-tos are available on the opensourcelowtech.org website.
A couple people have asked if I sell the file for the 3D printed impeller. I don’t, it’s free:
STL (mesh, 28 MB): https://drive.google.com/open?id=18NuQbyD55YhnAM9aj_lBrWgHAxp3iZxE
Iges (nurbs, 14 MB): https://drive.google.com/open?id=1HL_y-HwpomukQ7ORQf2E57Zy7ytoWTKN
Feel free to play around and experiment with them however you like, but please let me know how it goes and what your results are, as that’s always good to see.
It seemed to work ok, but I’m going to instead be using computer cooling fans as they seem to do higher revs at lower toque, and be a lot more accessible in other parts of the world.

Sick of your phone running out of battery? Now you can use a mini water turbine to charge it up. With the invention already a success in India, the German engineer behind it now has his sights set on the African market.

Electricity is produced by a diversity of energy sources, and different types of technologies.
According to the U.S Energy Information Administration, in 2020:
– Natural gas represented the largest source of energy production, at about 40%
– Coal represented about 19%
– Petroleum at 1%
– Nuclear energy, producing electricity from nuclear fission, represented 20%
As for renewable energies, those have been rapidly varying their share of U.S. electricity.
The total amount of electricity produced by renewable energy in the U.S is about 20%.
Here is a breakdown in 2020:
– Hydropower plants produce about 7.3%
– Wind Generation: 8.4%
– Biomass: 1.4%
– Solar: 2.3%
– Geothermal: 0.5%
Renewable energy has become a very hot topic in today’s world. We see and hear more every day about solar and wind power generation.
What we don’t talk about, however, is that with the increased use of wind and solar energy, comes the increased concern about grid stability.
The equilibrium between how much load is generated, and how much load is required by the grid is a continuous balancing act, which needs stability and is crucial in order to avoid blackouts. The energy generated needs to constantly be equal to the energy consumed.
When it comes to generating power via the use of wind or solar energy, there are uncertainties that need to be accounted for: Either the sun is bright and shining, or it is not. Either you have wind making your turbines spin, or you don’t.
What we are doing by the addition of those energy sources is essentially adding more and more instability to the grid.
This is where hydropower comes in… not only do the hydropower plants have the ability to store fuel (or water!), they also have the ability to respond to grid variations, also referred to as load requests within fragments of a second due to its governing systems that control the turbine’s speed.
That is why hydropower is often referred to as the Guardian of the Grid!
How is hydropower actually generated?
Well… the energy is generated by the same principles ancient Greek farmers used to grind grain: the flowing water spinning a wheel or a turbine.
Hydroelectric power plants are always located near a water source due to the fact that water is the source of hydroelectric power.
Inside the power plants, there are different types of turbines, but for today, we will look into the turbine known as the Francis turbine or the friendly Francis. It takes the friendly nickname due to being less complex to control, with fewer parts and fewer variables.
The difference in elevation, created by the dam, between water level from intake and discharge is what is referred to as head.
With the exception of the not-so-common diversion turbine, which relies on the natural flow of water to create motion, hydro turbines are often built at a lower elevation.
Francis turbines require a low and medium head. This means that the dam is smaller than when compared to the dams needed for the other turbine’s head’s requirements.
Wicket gates are how governors can control the speed of the turbine!
The turbine then turns the attached shaft which spins your generator, to produce electricity. That electricity then travels through power lines all the way to your home… and gives you light!
We have two other types of turbines, the Kaplan and the Pelton turbine.
– A Kaplan turbine has not only gates but also blades!
– A Pelton Turbine spins on air just like the Greek farmer’s wheels.

Ana’s has lived alone here for a while, The electric power system that Ana’s is using is powered by a small 1000w turbine. After building the small cabin, Ana’s needed to install the electrical system for the house. Today Ana’s will upgrade the flow and ensure enough water for Ana’s hydroelectric system to work properly and provide enough electricity for Ana’s house. Do you see Ana’s installed correctly? Please leave your comments in the comments section. Hope you guys enjoy the work Ana’s is doing and See you in the next videos on Ana’s bushcraft channel.

Ka-Yen’s lecture on how nuclear reactors work is expanded upon, to spend more time on advanced fission and fusion reactors. Lots of topics related to reactor operation are conceptually introduced – moderation, absorption, leakage, fast vs. thermal spectrum, breeding fuel, neutron poisons, and temperature/density feedback. This sets the stage for student control of the MIT reactor to come shortly.

This off-grid hydro power system has a major problem; too much power. Jeff has stumbled upon a small clan of off-grid homeschoolers and discovers that their power system is a major source of angst.
Their stream engine produces around 1200-1300 Watts continuously and their load controller must get rid of any excess power by dumping the power into a hot water tank. Image the struggle to use copious amounts of hot water!
Anything with the word nuclear next to it usually comes with a fair bit of misunderstanding. Hopefully this video demystifies the process of how nuclear fuels are turned into electricity and how we can use them in combination with renewables in order to reduce greenhouse gas emissions and the effects on the climate that come with high levels of them.
Of course, there are many things that have been left out this video as nuclear energy, just as with any other source, has many different factors that need to be taken into account when making decisions. In order to fully understand the situation and make decisions, I highly recommend that you do some research of your own on the topic, rather than simply base your opinion on a four-minute YouTube video.
It should also be noted that this video has been made from the perspective of the United States in general. Every area on Earth has different natural resources and environments that determine what works best there.

Hydropower has been the largest global provider of renewable electricity for over 100 years and represents the first mainstream source of renewable energy. However, many environmental groups don’t view large-scale hydro as truly renewable. So what is it? Is hydroelectricity a foundation of our energy future or something better left in our past?
